WATCH-CASE SPRING.

SPECIFICATION forming part of Letters Patent No. 311,563, dated February 3, 1885.

Application filed February 14, 1884. (No model.)

.To all whom it may concern:

Be it known that I, THEOPHILOUS L. BEAR, a citizen of the United States. and a resident of the city of Camden, State of New Jersey, have invented a new and useful Improvement in VVatch-Case Springs, of which the following is a specification.

In the accompanying drawings, Figure 1 represents a cross-section of the case, showing the spring in position. Fig. 2 is a vertical view, the spring being indicated by dotted lines. Fig. 3 is a cross-section of the rim of case at the point indicated by the line 1 2, Fig. 2. Fig. 4 is a vertical View of spring, andFig. 5 is a side view.

The device consists of a spring which is capable of being readily fitted to a case of any shape, and when in place admits of being ad justed. This is accomplished by two adjusting-screws passing vertically through the body of the spring. These screws are shown at A A in Fig. 1. In fitting they are filed so that the spring can be pushed in just far enough to receive the clamping-screw B. Their ends will then rest above and below on the case, as shown in Fig. 3. The effect of turning either one of the screws A will be to change the plane of the spring relatively to that of the case. They are turned by means of pliers grasping them be- 30 tween the spring and the case.

By this arrangeinent it is possible to raise or lower the end of the spring, which is not the ease, to my knowledge, with any known device. One great advantage is, that hammering the spring will be avoided, that being the present method of accomplishing the vertical adjustment, otten resulting in breaking the spring or rendering it more liable to break. An additional advantage is, that in the event of the screw B becoming rusted, pliers can be introduced between the rim of the case and the spring; or, by turning the screws A A, the screw B may be made to project above the rim of the case, thus permitting a firmer hold to be obtained than by a screw-driver.

The device is applicable to either the catch or raising-spring.

I claim 1. The CODlblllZLtlOlLlll a watch-case spring, of a screw or screws passing vertically through the body of the springfor the purpose of pro ducing a vertical adj ustnient, substantially as set forth.

2. The combination,in a watch-case spring, of the screws A A and the screw B, substantially as set forth.
